Final answer:
Without the specific techniques mentioned by Dr. Vaughn, generic but important communication skills for engineering include active listening, clear language, non-verbal communication, and constructive feedback.
Step-by-step explanation:
The question concerning Dr. Vaughn's techniques for better communication falls under the field of Engineering, which often encompasses soft skills like communication in addition to technical proficiencies. Unfortunately, without specific details on the four techniques Dr. Vaughn mentioned, it is challenging to provide the correct answers. However, common communication techniques that are often taught to enhance communication in the engineering field include:
- Active listening - Engaging actively with the speaker, confirming understanding, and asking questions for clarity.
- Clear and concise language - Using direct and simple language to avoid misunderstandings.
- Non-verbal communication - Understanding and utilizing body language and other cues to communicate effectively.
- Feedback - Giving and receiving feedback constructively to improve mutual understanding and work outcomes.
